I once drove a porsche GT3 (few months ago) on a track : believe me, you won't push the pedal to metal in low gear and you'd better brake BEFORE downshift or you'll learn quickly what gearbox locking (and spinning mean). Ok, this was not really a race car, but 350+HP for this weight and slick tires give me a good approach (also tried a F355 modified for Challenge)
Most people (including me) have driven too many arcade games to think to compare to a real car... As said before, a race car (expecially tuned) has nothing to do with the car you drive everyday (uch, much more BRUTAL behaviour - slicks are really impressive) nor with a pseudo car in an arcade game (where you might oversteer and follow your line with full gas or full brake...)
Subject is close for me... And even if the tyres are a little too slippy (I hate this Fo8...), I see that some expert racers drive them without pb (and 10s pro lap quicker than me - I feel such a lamer) so I understand *I* need to improve rather than harass the dev... Each car is specific, each track is specific and you'll have to be comfortable with all of combinations...
For people finding turbo cars too hard to drive, think to the stupid preparators who modify the engine without changing the shocks or transmission. The car has been designed to be coherent by quite a lot of engineers (including me for some of them which should definitively be a sign of quality 0:-) ), so how the hell could the first "expert in tuning" modify the car? (ok, I'm off subject and angry). I do not hate tuners, I do not hate tunng, I hate idiots, that's different. The problem is that both categories often mix together... (I think I'll be moderated) (I apologize in advance)
